How often do you contemplate your nervous system? For the majority of people, the answer would probably be not that frequently. As long as your body is performing as it is supposed to, you’ve no reason to consider how your neurons are firing or whether nerves are sending proper messages through the electrical pathways of your body. But you tend to take a closer look when something isn’t working right and the nerves start to misfire.

One distinct disease called Charot-Marie-Tooth Disease which generally affects the extremities can also have a pretty wide-scale affect on the entire nervous system. high-frequency hearing loss can also be triggered by CMT according to some evidence.

Charot-Marie-Tooth Disease, What is it?

Charcot-Marie-Tooth disease is a set of inherited disorders. Effectively, these genetic conditions cause something to go wrong with your nerves or with the protective sheathing surrounding your nerves.

The result is that the signals sent from your brain to those nerves (and from those nerves back to your brain) don’t work all that well. A loss of motor function and sensation can be the outcome.

CMT can be present in several variations and a combination of genetic considerations normally lead to its expressions. Symptoms of CMT commonly begin in the feet and go up to the arms. And, strangely, among those who have CMT, there is a higher rate of occurrence of high-frequency hearing loss.

The Cochlear Nerve: A Connection Between CMT and Loss of Hearing

The connection between CMT and loss of hearing has always been colloquially supported (that is, everyone knows somebody who has a tells about it – at least within the CMT culture). And it seemed to confuse people who suffered from CMT – the ear didn’t appear all that related to the loss of feeling in the legs, for example.

A scientific study firmly established the connection just recently when a group of scientists evaluated 79 people with CMT at the University of Iowa Hospitals and Clinics.

The findings were rather decisive. Nearly everyone who has CMT passed their low and moderate frequency hearing assessments with flying colors. But all of the participants showed hearing loss when it came to the high-frequency sounds (usually across the moderate levels). Based on this study, it seems probable that CMT can at least be connected to high-frequency hearing loss.

What is The Cause of Hearing Loss And How Can it be Treated?

The link between high-frequency hearing loss and CMT might, at first, seem perplexing. But all of your body, from your toes to your eyebrows, relies on the proper functioning of nerves. Your ears are exactly the same.

The hypothesis is, CMT affects the cochlear nerve so sounds in the high-frequency range aren’t able to be translated. Anyone with this type of hearing loss will have a hard time hearing some sounds, including voices. Particularly, make out voices in crowded or noisy rooms can be a tangible obstacle.

This form of hearing loss is normally treated with hearing aids. There’s no known cure for CMT. Modern hearing aids can offer tremendous help in terms of overcoming the effects of high-frequency loss of hearing, selecting only those ranges of sounds to amplify. The majority of modern hearing aids can also do well in noisy environments.

There Can be Numerous Causes For Hearing Loss

Further than the unconfirmed hypothesis, it’s still not well understood what the link between CMT and high-frequency hearing loss. But this type of hearing loss can be efficiently treated with hearing aids. So scheduling an appointment to get fitted for hearing aids will be a good choice for people who suffer from CMT.

Hearing loss symptoms can occur for a number of reasons. Commonly, it’s an issue of loud noise contributing to damage to the ears. In other circumstances, loss of hearing could be the result of an obstruction. It also looks as if CMT is another possible cause.
